Abstract
A retractable radome assembly is comprised of a number of hollow casings having successively smaller transverse dimensions, disposed to permit nesting of a smaller dimension casing within a next adjacent larger dimension casing in a vacuum sealing relationship and in such a manner as to permit relative mobility of adjacent casings in a coaxial telescoping manner from a fully retracted to a fully extended coaxial position. The casing sections are maintained in the fully extended position through forces created by a differential pressure between the outside atmosphere and a vacuum atmosphere provided within the casing wall structure, the radome being maintained in the fully retracted position through the use of mechanical retracting assembly applied in the absence of a vacuum atmosphere within the wall structure.
